switch-on/off), functional test, preset settings, fitting the options and mounting
the unit into a 19" rack.
Chapter 2 explains the manual control of SMIQ. It contains front and rear panel views,
describes the control elements as well as connectors, provides a short
introduction with sample settings for first-time users. It also explains how to
change parameters and the use of the list editor and gives an overview of the
menus for the functions covered by the unit and its options. It also presents
the functions and menus of the unit and its options (frequency and level
setting, analog and digital modulation, ARB, external modulation source
AMIQ, fading simulation, noise generation and distortion simulation, BERT,
sweep, LIST mode, memory sequence and general functions not relating to
signal generation).
